Perl300 has asked for the wisdom of the Perl Monks concerning the following question:
Hello Monks,
I am trying to perform specific tasks in my CGI script depending on if the "Submit" button is clicked or not. Basically, I have a dynamic webpage and I am trying to ensure that when the page is first called from browser, some code should be skipped. To do this, I am trying to put a check for Submit button. I am trying to use $query->param('submit') with a sample code (Test.pl) like:
With this code when I access Test.pl from browser, it shows the page with submit button, but even after I click on submit nothing is stored $a. Can you please help me find what I am missing here? My final goal is to run a chunk of code when the webpage is just fetched but Submit button is not clicked. After submit button is clicked, I am showing the resulting data in the same page.
